Definitions

  • a monitoring means for monitoring a number of carrier frequencies assigned to a said beam
  • Each transceiver TX 1 -TX n operates at a respective different carrier frequency, and carries a plurality of communications channels, for example in the form of time division multiple access time slots.
  • a carrier frequency may be allocated to any one of a plurality of beams formed by the antenna array 806, and beam former matrix 807, the corresponding transceiver being switched to the appropriate selected beam by the switch and combiner matrix 801, under control of the control unit 805.
  • FIG. 11 there is illustrated an example of data held by the monitor unit 804 and control unit 805.
  • This example related to a time division multiplexer system, where each transceiver operating at a corresponding carrier frequency carries a plurality of time division multiplexed channels.
  • the data held includes a list of each of the beams B1-B7, and their corresponding frequencies currently comprising those beams, and the corresponding communication channels, each corresponding to a respective transceiver carried by those carrier frequencies.
  • beam B1 comprises carrier frequencies f 1 , f 7 , f 12 , f 20 , f 31 .
